- An inexpensive construction of the device results from the fact that only one Measuring unit with at least two image recording devices is provided, and that the wheel and axle geometry data when driving past first for one Vehicle side and then for the other side of the vehicle when repeating Passing from the other side can be determined.
- Extended measurement options compared to a one-sided arrangement of a Measuring unit are achieved in that with only one measuring unit from only one Position at least three reference features per vehicle side, the wheel features of the Wheels of at least one vehicle axle and at least one body feature the wheel characteristics of the wheels at the same time and at least in the course of the passage of all vehicle axles and the assigned body feature (s) at least sequentially or simultaneously detected or that to determine the Wheel and axle geometry on both sides of the vehicle with a one-off Pass a measuring unit with at least on both sides of the measuring station two image recording devices is provided.
- the Device can also the wheel offset, the side offset, the Track offset and the axle offset next to the track for each wheel that Total track and camber determined for each wheel in the evaluation device become.
- a measuring unit comprises at least three image recording devices.
- At least one light source near the Objective of the image recording device (s) favors the detectability of retroreflective Measurement and reference features. It is provided that the light sources Send light outside the visually perceptible spectrum, e.g. Infrared LEDs are, there will be an impairment of the lighting conditions for the Device operators avoided at the measuring location.
- the wheel characteristics, the wheels of several vehicles or several measuring stations can be automatically distinguished by the fact that at least one wheel feature and / or at least one body feature and / or at least one Reference feature carries a code that can be detected by the image recording device.
- Wheel brands per wheel By attaching several wheel brands and coding at least one of them Wheel brands per wheel, it is also possible, in particular, the amount of one To determine the shape error of a rim and the corresponding wheel brand assign and if necessary in the subsequent measurements or evaluations to take into account or to correct.
- Fig. 1 and Fig. 3 show a device for determining the wheel and Axle geometry of a vehicle while driving with the side of the wheels 5 measuring units 1 arranged on a tripod and between them and the reference feature arrangements 3 arranged on the wheels 5.
- each of the measuring units 1 has two image recording devices in the present case in the form of cameras 2, which have an image section 6 in which both the wheel 5 and the reference feature arrangement 3 at least partially as well as a body brand 7 simultaneously during one Drive past the vehicle.
